Nano‐Topography Enhanced Topological‐Cell‐Analysis in Radiation‐Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
Radiotherapy, a treatment that implies exposition of cells to radiation, offers promise to treat cancer. Here, it is hypothesized that the nanoscale details of a scaffold can amplify the response of cells to radiation, measured through topological variables, providing ways to assess the efficacy of Radiotherapy treatment.

Modulating Trapping in Low‐Dimensional Lead–Tin Halides for Energy‐Efficient Neuromorphic Electronics

open access: yesAdvanced Materials, EarlyView.
Robust 2D Ruddlesden–Popper lead‐tin perovskites demonstrate exceptional resistive switching memory performance after cesium carbonate deposition, achieving a high accuracy of 90.1% in MNIST pattern recognition. Additionally, a novel energy‐efficient content‐addressable memory architecture, based on perovskite memristive devices, is proposed for ...
